Metal strip under door 50 DeSoto

[BillMurphy]

There is a metal strip under the front door (drivers) that seems to have what's left of the weatherstrip attached to it. There has to be a reason for it. I was wondering if I should reuse it or try and duplicate it if it's too far gone. Any ideas on its purpose? Have you reused yours or just glued the weatherstrip directly to the door? Thanks, Bill

The metal strip was originally encased by the weatherstrip and had tabs which went through the bottom of the door to make sure the weatherstrip stayed in place.  Use a good commercial grade weatherstrip adhesive and you will be ok  except when the weather conspires to freeze the strip to both door and body.

thin coat of Vaseline on rubber where it may make contact and freeze in such clime will prevent sticking

Now it makes sense, Thank You!
